    self.view.backgroundcolor=[[uicolor alloc] initwithred:0.3f green:0.35f blue:0.85f alpha:1.0f];
    
    uiview *view1=[[uiview alloc] initwithframe:cgrectmake(0, 0, 100, 100)]//创建view ，view是矩形，0，0表示左上角坐标，后面的100，100代表宽高
    view1.backgroundcolor=[[uicolor alloc] initwithred:0.88f green:0.66f blue:0.11f alpha:0.8f];//给新创建的view设置背景颜色，便于观察
    [self.view addsubview:view1];//向viewcontroller中的view中添加子view
    
    //下面代码都是对上面的复制和修改，仅仅是坐标和颜色不同
    uiview *view2=[[uiview alloc] initwithframe:cgrectmake(30, 30, 100, 100)];
    view2.backgroundcolor=[[uicolor alloc] initwithred:1.0f green:0.0f blue:0.6f alpha:0.8f];
    [self.view addsubview:view2];
